Title: Ethylenediaminetertraacetic acid or its ammonium salt semiconductor process residue removal composition and process
Inventor: LEE WAI MUN
IPC: C11D3/34
Filed: 1998-03-23
Granted: 2001-01-01
Abstract: An ethylenediaminetetraacetic acid or a mono-di-tri-or tetraammonium salt 5 thereof residue cleaning composition removes photoresist and other residue from integrated circuit substrates. The balance of the composition is desirably made up of water, preferably high purity deionized water, or another suitable polar solvent. A process for removing photoresist or other residue from a substrate, such as an integrated circuit semiconductor wafer including titanium metallurgy, comprises contacting the substrate with the composition for a time and at a temperature sufficient to remove the photoresist or other residue from the substrate. Use of the ethylenediaminetetraacetic acid or a mono-di-tri-or tetraammonium salt thereof in the composition and process provides superior residue removal without attacking titanium or other metallurgy, oxide or nitride layers on the substrate.

Title: Dynamic random access memory and stacked capacitor structure without escaping hemisphereical particle silicon layer and array variation
Inventor: LIN DA-CHENG
IPC: H01L27/108
Filed: 1998-06-16
Granted: 2000-07-01
Abstract: This is a stacked capacitor with larger surface area. The method uses the hemispherical particle silicon layer and heavily doped amorphous silicon layer as a store lower electrode. The formation of the hemispherical particle silicon layer stored in the lower electrode surface includes providing a transmission gate transistor on a semiconductor substrate. The transmission gate transistor includes a polysilicon gate structure formed on the gate isolation layer and a source/drain region deposited on the semiconductor substrate. A contact window of the store lower electrode on the isolation layer is formed; the source region's upper surface in the contact window is exposed. The store lower electrode is formed by wet acid pre-wash to remove the native oxide on the surface of the lower electrode. A first amorphous silicon layer in the store lower electrode and the first contact opening between the lower electrodes are deposited. A second contact opening between the lower electrodes is formed. A second amorphous silicon layer is deposited over the first amorphous silicon layer and forms a third contact opening between the lower electrodes. Long seed and anneal process converts the second amorphous silicon layer to a hemispherical particle silicon layer. A dielectric layer is formed over the hemispherical particle silicon layer. A polysilicon layer is deposited over the dielectric layer. A photo-resistant pattern is formed on the polysilicon layer. The photo-resistant pattern is used as a mask to define the polysilicon layer by etching technology to form the lower electrode of the stacked capacitor. The dielectric layer is defined over the hemispherical particle silicon layer to form the dielectric layers of the stacked capacitor upper and lower electrode. The first amorphous silicon layer is defined to form a polysilicon upper electrode of the stacked capacitor. A fourth contact opening is formed between the lower electrodes.

Title: New reference memory cell array to provide reference current for the sensing amplifier
Inventor: CHR YU-DE
IPC: G11C11/00
Filed: 1999-12-27
Granted: 2003-06-01
Abstract: A kind of reference memory cell array for providing comparison of reference voltage when reading the memory cell is disclosed in the present invention. The invention contains plural memory cells, which are divided into the upper and lower parts by using a common source line as the symmetrical face. Each of the upper and the lower parts has two word lines connected to a power source supply terminal; but the outermost word line is connected to a decoder for selecting one as the active state. In addition, each reference bit line has a bit line contacting with an isolation region for terminating the connection of the common source region; and the contact between the isolation and the bit line is located at different portions and is distributed in a interlaced manner such that the odd-numbered bit line is located at the lower half part even when the even-numbered bit line contact is located at the drain of the outermost row of memory cell in the upper half part. Furthermore, the entire floating gates are connected to a defined electric potential. Because each bit line is connected with only three memory cells, it is capable of providing about one third regular memory cell current so as to be beneficial for providing a reliable comparison voltage.
